At one point during the new trailer for "Jodorowsky's Dune," Chilean
filmmaker Alejandro Jodorowsky refers to his old passion project as "a
film that gives LSD hallucinations — without taking LSD ... to change
the young minds of all the world." Given that this could easily describe
most of Jodorowsky's films, it's a shame it never got made. But Frank Pavich's documentary "Jodorowsky's Dune" offers the next best thing: a look at what might have been.

There are plenty of unrealized films that cinephiles would love to have seen made, but few more bizarre or more fascinating than Jodorowsky's version of Frank Herbert's masterpiece "Dune." The cult director behind "El Topo" and "The Holy Mountain" had a wild vision planned: designs by H.R. Giger, music by Pink Floyd, and cast that would have included Mick Jagger, Orson Welles, and Salvador Dali, among others.

The film was never made – it was too expensive, and perhaps a bit too nuts for a studio to fund (though David Lynch's messy version wasn't much more accessible) – but aspects of the project's designs would go on to influence "Alien" and "Blade Runner," among other projects. Including interviews from Jodorowsky, producer Michel Seydoux, and noted fans like Nicolas Winding Refn, the documentary has been a big hit on the festival circuit since its debut at Cannes last year. The film finally hits the U.S. March 7.
